ROI ERT S. BROWN, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE NEW BRITAIN MACHINE COMPANY, OF NEW BRITAIN, CONNECTICUT, A CORPORATION OF CON- N ECTICUT.

To all whom it may concern;

Be it known that I, Ronnn'r S. BnowN, a citizen of the United States, residing at New Britain, in the count-y of Hartford and State of Connecticut, have invented certain new and useful Improvements in Journal- Bearings, of which the following is a specification.

This invention relates to journal bearings the object of the invention being to provide a simple article of this character wherein efiective lubrication of the surface or surfaces to be lubricated is assured and wherein access to certain of the parts can be readily and quickly secured.

The device possesses other features of advantage which with the foregoing will be set forth at length in the following descript-ion wherein I outline in detail that form of embodiment of the invention which I have selected for illustration in the drawings accompanying and forming part of the present description. This specific disclosure is to enable those skilled in the art to practice the invention. I wish it to be understood that I do not restrict myself to such showing as many deviations may be adopted within the 'scope of my invention as expressed in the claims succeeding said description.

Referring to said drawings, Figure 1 is a front elevation 1partly in scction,'of.journal bearings invo ving my invention. Fig. 2 is 'a transverse section ofthe body portion of a box and the base member of a bearing I showing particularly the. manner of removing said base member. Figs. 3 and 4 are top and bot-tom plan views respectively of the upper portion of'a bearing, and, Fig. 5 is a topplan view of said base member.

ike characters refer to like parts throughout the several figures.

A journal bearing comprising my invention can be employed with advantage in many different connections. In Fig. 1 of the drawings I have represented two of such bearings in combination with the shaft and certain other elements of a well known type of grinding machine the framework of which is denoted in a general way by 2. The shaft which carries the grinding Wheel (not shown) is designated by 3 and to it is fastened a suitable driver as the. pulley 4 the operating belt for which is denoted by 5. These several parts are common in cer- Specification of Letters Patent.

JOURNAL-BEARING.

Patented Sept. 19, 1911.

tain classes of grinding machines for which reason it is unnecessary to describe them in detail. I employ two bearings for the shaft as it is the custom to do so there are or may be instances where one bearing might answer the' purpose at hand. As the two bearin s are sim1lar in construction I will descri e but one of them in detail similar arts in the other where they appear bearing like identifying symbols.

he shaft 3 has a journal ortion 6' and I make provision for thoroug 11y lubricating the same as will hereinafter appear. This journal portion is inclosed by and turns in a hearing within a box such as that denoted in a general way by 7 which though normally stationary has provision for adjustment longitudinally of the shaft 3 for a purpose that will hereinafter appear. The box 7 is supported by the framework 2 and it is shown as consisting of a lower portion 9 and an upper portion 10 which are fitted somewhat closely together and united in some desirable manner for instance by screws 11. The lower portion 9 has an under flattened face so that it can freely slide on the framework 2 the box as a whole being held in an adjusted position by a holding screw 12 tapped into said lower portion 9 and extending through a slot 13 formed in the flange 14 of the framing 2 and elongated in the direction of the length of the shaft 3. The head of the screw by acting against the flange 14 maintains the said box in an adjusted position and the adjustmentcan be easily changed by backing out the screw. The said box 7 presents a convenient means for 'inclosing the bearing proper and which I will hereinafter refer to simply as the bearing. Such a bearing as answers effectively my purpose is de-' noted in a general Way by 15. The bearing 15 consists preferably of two members as 16 and 17 which are made practically in the form of elongated shells which-comparatively closely fit or hug the journal portion 6. The said bearing 15 is so mounted that it is capable of universal movement by virtue of which it can automatically aline itself with the shaft 3 and avoid the possibility of binding, and I will hereinafter describe a means whereby the function in question can be effectively and simply secured.

Within the box 7 and preferably on the lower portion or section 9 thereof I form a 55 unison or as one.

flange or rib as 18 which is shown as being situated substantially midway of the said box although the particulardisposition thereof is not a matterof prime consideration. The upper surface 19 of this rib or. flange is shown as being of channel form and preferably spherical to present a'seat for the like spherical surface on a rib or flange as' 20 formed on the exterior of the lower bearing or base member 16., This relation as will be apparent prevents possi .bility of the said base member 16 having any endwise movement although it is free to rock longitudinally and laterally. It will 5 be obvious that by the described construction it Wlll be a very simple and easy matter to remove the bearing without dismounting the shaft 3 or disturbing any of the parts associated with said shaft. To remove said-bearing it will be of course first necessary to take off the cap portion 10 of the box 7 after which the bearing member 17 will be lifted off the complemental bearing member 16. The latter will then be slipped from place by a lateral sliding motion as shown in Fig. 2. This operation is one which can be quickly and easily performed and the parts can be reassembled just as readily, the two described ribs acting as positioning means of a positive and certain nature to definitely and precisely locate the lower or base member of the bearing 15. It will be understood that except for the slight universal movement of said bearing the latter is stationary.

While the two members or shells of the bearing 15 fit thejournal portion 6 somewhat snugly there is no contact between said two members their lateral edges being separated or spaced apart so as to provide for a better distribution of the lubricant. The upper section or shell 17 is held in proper relationby somev suitable means such as by the screw 21 represented as tapped through the cap portion 10 and the reduced lower end or tip of which fits freely in a depression or pocket as 22 formed in a rib 23 formed externally of the member 17. This relation permits the .upper member 17 to rock or oscillate longitudinally and laterupper section of the bearing 15 bodily with I the box 7 as the latter is adjusted longitudinally of the shaft 3 by reason of which I can always insure a proper relation between a scraping shoulder and a collar both hereinafter described.

. On the inner surfaces of the bearing members 16 and 17 are complemental semi-annular channels 24 and 25 which jointly receive thefcollar 26 on the journal portion 6 and their function will be hereinafter set forth. At this point I should state that the lower section 9. of the box 7 constitutes an 011-rece ver or reservoir the 011 being fed into said section 9 substantially up to the level shown in Figs. land 2 and the collar 26 in connection with the two channels or grooves in connection with other means' hereinafter described, serving to lubricate thoroughly the journal portion 6 throughout its entire area. The two grooves or channels 24 and 25 are shown as extending into the ribs 20 and 23 respectively.

The lower box section 9 is shown as havinga filling opening 27 which receives the I familiar oiler 28 and by which oil can be introduced into said section 9. The transverse rib 18 in the section 9 has two ports or passages as 29 through which oil can flow from one side of said rib to the other therefrom by the rotating collar 26. It will be obvious that the level of the oil in the trough or groove 2& is the same as that in the section 9.

The collar 26 runs in oil in the trough or groove24and as the sha-ft3 turns said collar lifts positively oil from said trough up into the groove or chamber 25 where the oil is positively scraped from said collar and diverted sidewi'se as will hereinafter appear. The groove or chamber 25 is widened as at 31 by reason of which there are produced two scraping portions or shoulders 32. Initially both scraping portions separate the oil from the side faces of the collar 26 but in time the parts will naturally become worn and in this event the box 7 will be so adjusted that one of the said scraping p0rtions will act and I provide means of such a nature that even though but one of said scraping portions be in actionthe opposite ends ofthe journal portion 6 will be adequately lubricated. The oil scraped from the collar 26 passes oppositely (if both shoulders 32 be in action) through the opposite ports 33 extending through the rib and into pockets 34. The oil flows from these pockets into the entering ends of obtuse angular channels 35 in the rib 23, Fromv opposite ends of each of these obtuse angular channels 35 branch channels as 35' extend, there being as will be apparent four of these branch channels and-each of 'them extending obliquely of the upper bearing member 17 externally thereof and being formed preferably directly therein. .Said branch channels have at their outer terminooaeae port 33 supplies two cooperating branch channels 35 so that if only one of the scraping shoulders 32 be in action the oil will positively be caused to pass through two substantially alined ports. Looking at the construction set forth it might be considered that each channel 35 with its branches 35 presents a continuous channel extending longitudinally but irregularly along the exterior of the member 17 said channel having an inlet between its ends and outlets at opposite sides of said inlet. It will be perceived that this continuous channel or passage is so disposed that itcan conduct the lubricant oppositely which flows thereinto from the port 0 ening into the same between the ends thereo Owing to the construction of the member 17 it may be reversibly mounted'so as to positively cause one of the scraping shoulders 32 to operate irrespective of the direction in which the shaft 3 is rotating. The member 17 is provided on its outside with an arrow 37 stamped, cast or otherwise suitablyformed thereon to indicate the direction of rotation of the shaft.

The shaft 3 as it is heated up expands longitudinally and to .assure easy running thereof under such conditionsthe following expedient is adopted. The two collars 26 are so related with the bearings 15 thatthe inner faces of the said collars are contiguous to the inner walls of the semi-circular grooves so that when the shaft expands longitudinally the collars will move away from said inner Walls.
